    Page 29 3.7. Application Examples Despite its capability of showing simultaneously input and output functions in the display, there is no isolation between V and mA input and output signals. This means that when the calibrator is connected to a converter (I / V, V / I, I / I or V / V) it may not work properly or the set could be damaged, in case the converter is not galvanically isolated.

  • Page 42: Cal Function

    Page 41 Fig. 22 – SCALE Function (FLOW) 3.9.2. CAL Function The calibrator may be used to calibrate or check isolated converters. In a typical application, it would “generate” a pressure signal and measure the current signal from a pressure transmitter. Due to reasons of quickness and easiness to compare errors at the input and output of the converter, the reading of the calibrator current input can be displayed in the same unit of the generated signal, i.e., pressure...

  • Page 45 Page 44 Fig. 24 – SCALE Function (LINEAR) Scale Dec parameter configures the decimals presented on the display. The value of Output High must always be higher than Output Low. Scale Low and Scale High parameters may have any relationship between them, provided that they are different.
  • Page 46: Conv Function

    Page 45 Fig. 25 – SCALE Function (FLOW) 3.9.4. CONV Function By using the CONV function, calibrator may convert any input signal into mA or V output signal. It may therefore work as a non-isolated converter. Once input and output have been selected, you must fill in the four parameters shown in the next figure.
  • Page 47 Page 46 Fig. 26 – CONV Function The value of Output High must always be higher than Output Low. Input High and Input Low parameters must never be equal. Thus, any type of direct or reverse retransmission from input to output can be obtained. Scale and Conv functions may be disabled by selecting the NO option and pressing ENTER, as shown below: ...
